I have a document from Ancestry World Tree that indicates Jonathan Addis was married to Elizabeth Laughead. Jonathan was born, according to this document, about 1760 and died between 1840-1850 in Fayette County, PA. This same source indicates Jonathan was of French and English extraction, came from Lancaster, PA and purchased a farm in Franklin Township near Redstone Creek where he resided until his death. He and Elizabeth had six sons and three daughters, one of who was my greatgrandfather, Robinson.
I was born in Vanderbilt, PA and recently visted the grave sites of Robinson, his wife Sara Gore Addis. They are buried on the same plot as my grandfater, Samuel, and my grandmother, Jane,(Jenny) Johnson Addis.
I have a we bit more info on this branch of the Addis family, but I am just beginning to rellyreseach it. Let me know if I can be of any further help. Also, I would apprecite any info you have. What is yourbranch of rthe family?
